Application filed July 7, 1822. Serial No. 573,395.

To all whom it may concern: which the rail rests. The rail is held onthe Be it knownthat I, SIDNEY S. SMITH, a tie by means of a retainingspike of which 55 citizen of the United States, residing at 5 is thehead and 6 the shank.

On the back side of the lower end of the spike is a projection 18 formedopposite the projection 7, the upper end of said projection terminatingin the shoulder 17 Inclined edges or the projections 7 and 18 arepreferably parallel so that as the spike is lifted, the'lower end willslide out from the inclined portion of the slot which is formed withparallel, opposing surfaces.

From the lower end of the spike, the opening in the tie is continuedthrough the bottom oi the tie so that the entire opening can be clearedout before the spike and its keeper are inserted and whenever it isnecessary to do so. The spike and the keeper are locked together to holdthem in posi tion by double pin 20 extending through a suitable opening,halt oi which is in the spike and half in the keeper.

By the removal oi the pin 20 the keeper may be lifted by a bar under theprojection 13 and having thus loosened the spike the latter may bereadily pulled out from the recess in the tie.

It will be seen that my means of securing the rail and the tie togetherare extremely simple. The rail is held downwardby the strength. of thespike securely locked in the body of the concrete and whatever jar maycome by the use of the track the spike is held solidly in place,although easily reinoved when d sired.

The vertical opening through the tie is, 1 course, carefully formed soas to exactly contain the spike and its keeper and when they are inplace a solid body is formed,

firmly secured to the rail so that it cannot,

be disturbed by any jar or motion which may take place by the movementof the rail when in use. p

The device is designed to be used on both sides of the rail.
